Hydrostatic Pressure Testing
Certified hydrostatic testing services for water pipelines, rising mains, and infrastructure across the UK.
Hydrostatic testing is the industry-standard method for verifying the strength, integrity, and leak-tightness of water pipelines. It is essential for confirming that pipework is safe, compliant, and ready for service.
Key Benefits
React Commisioning LTD offers a comprehensive range of pressure testing services tailored to meet the diverse needs of the UK water industry. We utilise state-of-the-art equipment and adhere to strict safety protocols, ensuring accurate, reliable, and compliant testing.
Confirms Structural Integrity
Ensures the pipe or asset can safely withstand its designed operating pressure.
Detects Leaks & Weak Points
Finds issues before the system goes live, reducing the risk of failures and disruption
Essential for UK Commissioning
Required for most new installations and major projects to meet water industry standards.
Hydrostatic Testing Process
Our hydrostatic testing process begins with a thorough system preparation, where the pipeline is inspected, cleaned, and made ready for accurate testing. The pipework is then filled gradually to remove air pockets and stabilise water flow before controlled pressurisation is applied to reach the required test pressure. Throughout the test, pressure levels are closely monitored and digitally logged to identify any drops, leaks, or structural weaknesses. Once complete, we provide a fully documented report including pressure readings, observations, and certification to confirm whether the system meets industry standards and is safe for service.

All hydrostatic testing is carried out in accordance with UK water industry regulations and documented for commissioning and handover.
When Hydrostatic Testing Is Required
Hydrostatic testing is required in a wide range of situations, including the commissioning of new water mains, rising mains, and pumped systems, as well as after repairs, extensions, or modifications to existing pipework. It is also essential during refurbishment projects, when investigating suspected leaks, or when verifying that a system can safely operate at its designed pressure. Whether used for compliance, performance assessment, or to ensure system integrity before handover, hydrostatic testing provides the confidence that pipework is safe, reliable, and ready for service.
